Among extant large reptiles, juveniles often occupy different habitats from those of adults or subadults and thus avoid competition with and predation from the older animals; small juveniles often choose cryptic habitats because they are vulnerable to a wide variety of predators. Evidence from fossil humeri and femora of Early Permian reptiles collected from sediments of several distinct habita...

Environ. Enlomol. 12: 2%-298 (1983) ABSTRACT Sweep-nel sampling and pilfalllrapping were used 10 survey insects in weedy and weedfree soybean habitals. Weedy soybean habitats consisted of (I) grassy soybeans; (2) soybeans with broadleaf weeds; and (3) soybeans with broadleaf weeds and grasses. Insect species diversity was greater in weedy soybean habitats than in weed-free soybeans. Greatest di...

Social behavior of the prairie vole, Microtus ochrogaster, including monogamy, mate guarding, philopatry, communal nesting, and territoriality, evolved as an adaptation to habitats with low food prevalent in the original range of the species. These behaviors are associated with low population densities and low amplitudes of fluctuation characteristic of low food habitats. In particular, reprodu...

A survey of entomopathogenic nematodes (EPNs) belonging to the families Steinernematidae and Heterorhabditidae was conducted in three municipalities on the Pacific coast of the State of Colima, México, to determine their occurrence and recovery frequency and predominant plant species in cultivated and non-cultivated habitats. Nineteen soil samples were collected: seven from non-cultivated habit...

Malaria is the leading cause of death in Kenya highlands. Malaria is a vector-borne disease and mosquito is the vector that transmits the parasites from infected people to others. Controlling mosquito larval habitats is important in eradicating malaria. Modeling the spatially distributed mosquito larval habitats is challenging. This study explores a mosquito habitat modeling approach, which int...
